Deciduous; leafless for a period in July or August.

Leaf blades about 5.5-17 x 3-15 cm. Stellate hairs visible with a lens on the lower surface of the leaf blade. Twig bark strong and fibrous when stripped. Pores in the twig pith visible to the naked eye and readily visible with a lens.

Inflorescence about 4-10 cm long, densely stellate hairy. Pedicels about 5-9 mm long. Flowers densely stellate hairy, perianth tube campanulate or urceolate-campanulate, about 2.5-5 mm long, inner surface pubescent or glabrous, lobes 3-4 mm long, apices cohering. Anthers about 11-17, crowded into a globular head.

Follicles obovoid to oblong, about 5-8 x 3-4 cm, densely stellate hairy on the outer surface. Seeds ellipsoid, about 17 x 6-7 mm.

Cotyledons about 18-20 mm long, margin revolute. First pair of leaves ovate to narrowly cordate, apex acuminate, margins entire. Stipules linear, about 4-5 mm long, hairy. At the tenth leaf stage: leaf blade ovate or narrowly cordate, apex acuminate, base cordate, glabrous, about 5-7 main lateral veins each side of the midrib; stipules narrowly or linearly triangular. Seed germination time 11 to 25 days.

Occurs in WA, NT, CYP, NEQ, CEQ and southwards to north-eastern New South Wales. Altitudinal range from sea level to 500 m. Grows in monsoon forest, vine thickets, drier, more seasonal rain forest and quite well developed rain forest. Also occurs in New Guinea.

An interesting tree cultivated for its bright red boat-shaped fruits with black seeds. Trees are usually leafless while in fruit and flowering occurs just before the new leaves appear. Seeds are edible.

Aborigines in northern Queensland crushed leaves of this species and applied then to wounds. An infusion of the bark was applied or juice wrung from the inner bark was applied directly to the eyes. Cribb (1981).
